3 Claims. (CI. 3013) This invention relates to improvements in hair or any other substitute which will serve the purcutting devices, and its objects are as follows:-- pose of a pivot. The device also includes a comb First, to provide a hair cutting device in the which lies fiat on one of the scissors blades. form of a scissors having its blades reversed The scissors is reversed from the customary 5 from the customary order and having a comb order and cuts in the opposite way. The hair 5 mounted on the blades pivot in such a manner must be cut upwards or against its natural inthat a pair of screws threaded through one of clination. The blade 2 is superimposed on the the blades, when separately adjusted, will in blade 3,.and is herein to be regarded as the botturn adjust the comb, said screws having swivel tom blade.

In the drawing: If the comb were similarly mounted on the Figure 1 is a plan view of a scissors modified blade of an ordinary scissors as already pointed and provided with a comb in accordance with the out, the teeth would either point in the wrong invention, the scissors being viewed from the direction or if the scissors were held so as to make side which goes next to the hair in the operation them point in the right direction the other blade 25 of cutting. would be interposed between the comb and the Figure 2 is a section taken on the line 2-2 of skin, thus establishing a space which would make Figure 1. it impossible to do accurate hair cutting.

The underlying purpose of the invention is 2 and 3), the holes which accommodate the swivel that of hair cutting on human beings and on ends of the screws 8, 9 being large enough to animals, and for whatever other purpose the deenable the rocking of the back 7. Said screws 40 vice may be adaptable, and to enable doing the are threaded into the blade 2, and when the hancutting with a nicety and ease that will permit dles 11 are turned the screws are fed either foreven an unskilled person to approach the skill wardly or reversely so that the back 7 is rocked, of a barber. The device is intended to be opso to speak, in the direction of the length of the erated by either right or left handed persons, blade 2 thereby to set the teeth 12 in the de- 45 and one of the chief objects is to bring the comb sired position with respect to the blade. into close contact with the skin, and to permit In some instances it is desirable to fix the teeth such adjustments of it with respect to the blade 12 on a slant with respect to the back 7 (Fig. 3), that the hair can be cut to any desired degree in other words, bend them away at an angle from of closeness. the plane of the back. This brings the points of 50 Attention is directed to the drawing in which the teeth a little closer and more sharply against the device is generally designated 1 in each of the the skin. This slanting is not always adopted, chief modifications in Figures 1 and 4. The deas in the case of Figure l. vice includes flat (or substantially so) scissors The modification in Figure 4 is identical in 5 blades 2, 3 which are pivoted together by a pin 4 principle with that in Figure 1. Similar parts are denoted by corresponding reference characters distinguished by the exponent letter a, the only exception being the general designation 1 mentioned originally. The comb 5 is made adjustable with respect to the blade 2 but this time crosswise of the blade instead of longitudinally. The crosswise adjustment is a substitution for the slanting of the teeth 12 in Figure 2.

Small plates 13 are aflixed to the blade 2 in any suitable way (Fig. 5). These have upstanding ears 14 through which screws 15, or the like are driven into the ends of the comb back '7 as at 16 (Fig. 4) to provide pivotal mounts. The screws are fast in the comb back, but they are loose in the ears 14 so that the comb is readily turned upon adjustment of the screws 8*, 9 (Fig. 5). g

In Figure 1 the teeth 12 are all of the same length whereas in Figure 4 they are progressively shortened toward the point of the scissors. This grading of the teeth on an angle permits finer hair cutting, especially the trimming of short hair.

Figure 6 is a diagrammatic section which is intended to illustrate how the comb is to be curved or bent at 17 away from the plane of the back and toward the point of the scissors at a place where the teeth begin to shorten. Such a place would occur approximately at 18 in Figure 4. The teeth are not shown in Figure 6, but the reader will understand that they jut out from the back 7* away from the observer or into the paper, so to speak. The blade on which the comb is mounted is designated 2 the blade pivot 4 and the adjusting screws 8 9 In each of the three forms of the invention it is intended to make it possible to mount a comb upon either of the two blades of the scissors. For this purpose, the blade which, according to the present showing, is idle insofar as carrying a comb is concerned is provided with holes 19 (each modification), spaced as individually required, to take the various kinds of means used in making the mounting. A comb for cutting the hair either shorter or longer than possible with the comb 5, 5 would be attached at 19, and since a comb mounted upon either blade would be in the same relative position with respect to the scissors the latter is adapted for use by a right-handed operator in each case. In order to adapt the scissors to a left-handed 'operator it is intended to mount the comb, for example 5 (Fig. 1) on the opposite side of the same blade. The comb would have the same type of back illustrated in Figure 1, and in order that the screw 9 may make connection with the back in the same position shown but on the opposite side of the respective blade, it would be the other end of the pivot pin 4 that would go through the comb back 7, and not the reduced tip 20.

The operation is readily understood. Take the device in Figure 1 (or Figure 4) in the right hand. The thumb goes into the thumb hole of the blade 3, and one of the fingers into the hole of the blade 2. This places the comb 5 in the proper and natural position to enter the hair when the device is brought into the cutting operation. As the hair is caught up by the comb the scissors is closed, and cutting commences. For fine and more delicate cuttin the type in Figure 4 has an advantage over the type in Figure l in that the teeth near the point of the scissors are slanted.

In all cases the comb is pivotally mounted on one or the other of the two blades of a scissors in which the blades are reversed as compared with an ordinary scissors. This brings the comb next to the skin in theuse of the device in a natural cutting operation. The adjustment is such that the comb can be set at any of various angles with respect to its blade, the adjustment being made by the screws 8, 9 and locked by said screws when turning of the latter is ended. In other words, the screws will not turn of their own accord, the threads which enable the advance of the screws in either direction also preventing advance when the screws are not turned.

I claim: 7

1. A hair cutting device comprising scissors blades, a pivot connecting the blades, said pivot including an upstanding tip, a comb having its back superimposed on one of the blades length- Wise. and having a hole through which the tip is fitted thereby providing a pivotal mount for said back, and a pair of screws for the comb, threaded through said blade on opposite sides of the pivot, said screws having swivel connections with the back for separate adjustment of said screws.

2. A hair cutting device comprising a scissors, a comb and means by which its back is mounted on one of the blades, the teeth of said comb being bent away at an angle from the plane of the back.

3. A hair cutting device comprising a scissors, a comb consisting of a back and teeth, some of the teeth at one end of the comb being of lengths diminishing toward said end, that portion of the comb back having the diminishing teeth being bent toward the plane of the scissors, and means by which the comb is mounted on the scissors for transverse adjustment.
